Example Program

An example program for the keypad is available from the Crestron FTP

site (ftp://ftp.crestron.com/Examples

). Search for CNX-B12.SMW.

Programming with VT Pro-e

The CNX-B12 is capable of playing audio messages as system prompts

and responses. These files are recorded as WAV files on a PC using an

audio utility such as Sound Recorder that is packaged with Microsoft

Windows 95/98/Me/XP/NT/2000

™

. Files from other sources may also be

converted to an acceptable format by using this or a similar utility. Many

other audio utilities are available commercially or as shareware. The

CNX-B12 keypad accepts only the following WAV file format: PCM,

8KHz, mono, 8 bit. For more information about how to use Sound

Recorder, refer to its User’s Guide and extensive help information

provided with the software. Also, refer to the help file in VT Pro-e to

learn how to use its audio tool, Sound Manager, to attach WAV files to a

keypad project.

Pre-recorded WAV files for voice prompts and responses can be obtained

from the Wave Library of the Crestron FTP site (ftp://ftp.crestron.com).
